 If you have trouble with Qt creator code highlights, but not compilation, make sure you have the correct version of Clang installed. When testing, the Ubuntu had clang-10 installed when Qt depended on clang-8. Installing `clang-8` may solve this issue.
 
-Note: We have not been able to get the changing of the camera formats, resolutions or frame rates to work on Linux. It is possible that we didn't have all the necessary packets installed or that there is some sort of bug in qt multimedia/multimediawidgets on Ubuntu. Any information on this would be greatly appreciated.
